Our entire home was destroyed by fire and We decided to rebuild. We chose a contractor who used Big L for all of our windows and doors. Not once have I regretted using Big L. Their post sales service has been outstanding. there were a couple of small issues and the team was prompt, always friendly and courteous whenever they came to the house. Big L simply does it the right way. And they've done it every time. Thank you Big L!!!!
I had a giant bay window replaced in the Fall of 2020. I dealt with Xander for the quote. He was on time, friendly and knowledgeable. When the time came to install the window, they could not reuse the trim that they took off of the window so they went and purchased the trim I already had and installed that free of cost to me. I would highly recommend.
Big L replaced my front door and a large bay window. The sales rep presented several options in a variety of price ranges with detailed quotes for each and gave us a veterans discount. The installation team was the best. Polite and professional, they did great quality work and they did it in a timely fashion. We had one problem and Big L expedited the replacement, voluntarily compensated us for our trouble and brought additional manpower to make sure the job was completed in one day. I like this company and will use them again in the future.
Big L did a fast, efficient, and amazing job on our windows installation. We are completely satisfied with the job the crew did for us, plus they cleaned up beautifully. I’ll be sure to recommend them to friends and family
Thank you for installing the four windows for us yesterday. Everything from start to finish was truly professional! Will definitely use Big L again in the future!
Our Big L windows are still perfectly sealed and operational after 25 years!
